AutoCAD Based Calculations (Ribbon/Toolbar/Location)
Description:
Unhandled exception: Input string not in correct format
Cause:
1. Problem with Pipe Size Schedule, most likely a blank space or a missing 9998 marker
2. Pipe on pipe or two blocks in same location
3. Unsized pipe to a drain or dead end (Hcad v51)
4. Windows 10 corupted files
5. Bad block or layer in the drawing, usually created by another trade
Solution:
1. Check sizing schedule, check sizing and head count make sure there are no blank spaces. Select a few items and set them different, then back to original to shake it up a little
2. Run OVERKILL command on drawing. Be sure to uncheck the option "end to end" option at the bottom
3. A pipe feeding a drain was unsized and the pipe scheduler couldn't determine its diameter because no sprinklers were being fed. Specifically on the floating main off a gridded system. Size drain pipe and retry. (GAB 12/02/14)
4. Unknown at this time.
5. Export the System Boundary (SB) to a new drawing, then try the process again. Make sure to either insert the SB drawing to a new template, or use RBL to rebuild the layers in the SB drawing before starting the autocalc process again. [GAB 10/08/20]
